"This year, International Women’s Day was the most talked about topic on the platform, with conversation driven by the Women's March, which ranked in the top ten global list, as well as the #metoo movement," Mia Garlick, Facebook's director of policy for Australia and New Zealand, said in a statement.

In third was Australia's successful marriage equality vote, followed by the country's flag carrier Qantas — spurred by discussions over new aircraft and its involvement in the marriage equality debate.

Also in the top five was the death of Chris Cornell, the voice behind Soundgarden and Audioslave, who passed away in May.
